What two key factors are needed for mold to grow?

  1. Moisture and food

  2. Temperature and habitat

  3. Water activity and UVC

  4. Humidity and anaerobic conditions

The correct answer is: Moisture and food

To support the growth of mold, two critical factors are necessary: moisture and food. Mold thrives in environments where there is an adequate supply of moisture, as it is essential for the mold spores to germinate and grow. This moisture can come from various sources such as leaks, high humidity, or condensation. Additionally, mold requires a food source to sustain its growth. Organic materials like wood, drywall, and even dust provide the nutrients that mold needs to proliferate. Without both moisture and a suitable food source, mold cannot establish or grow effectively. This understanding of mold growth conditions is vital for preventing and controlling mold in indoor environments.
